Communications: Comparison of activation barriers for the Johari-Goldstein and alpha relaxations and its implications
The range of activation barrier heights for the Johari-Goldstein (JG) relaxation in glasses is shown to overlap the range for the main (alpha) relaxation, but to be on the average somewhat lower. This suggests the JG relaxation, like the alpha, involve transitions between megabasins in the energy la...
